본 발명은 선체 내벽에 고정되는 다수의 2차 단열패널로 이루어지는 2차 단열벽과, 2차 단열패널의 상부에 고정되는 다수의 1차 단열패널로 이루어지는 1차 단열벽을 포함하는 이중 방벽 구조의 액화천연가스 저장탱크에 있어서, 1차 단열패널과 2차 단열패널을 상호 고정시키는 고정장치는, 2차 단열패널의 상부에 고정되는 제1 베이스 플레이트; 하단부가 제1 베이스 플레이트에 체결되고 상단부가 위로 돌출되게 형성되는 2 이상의 스터드; 스터드가 관통 삽입되며 1차 단열패널의 하부 플레이트에 의해 지지되는 제2 베이스 플레이트; 스터드가 끼워지며 제2 베이스 플레이트 상에 지지되는 플랫와셔; 및 스터드의 둘레에 설치되어 고정장치에 상하방향으로 작용하는 하중을 흡수하는 스프링부재를 포함하는, 액화천연가스 저장탱크의 단열벽 고정장치를 제공한다.

    The present invention provides an insulation wall securing device for an LNG storage tank. In the LNG storage tank with a double barrier structure, which includes a secondary insulation wall consisting of a plurality of secondary insulation panels fixed to an inner wall of a hull, and a primary insulation wall consisting of a plurality of primary insulation panels secured on an upper portion of the secondary insulation panels, the securing device for securing the primary insulation panel and the secondary insulation panel to each other comprises: a first base plate secured on the upper portion of the secondary insulation panel; two or more studs having a lower end portion fastened to the first base plate and having an upper end portion protruding upward; a second base plate into which the stud is inserted to pass therethrough and which is supported by a lower plate of the primary insulation panel; a flat washer fitted with the stud and supported on the second base plate; and a spring member installed around the stud to absorb a load acting on the securing device in a vertical direction. Therefore, the insulation wall securing device increases the structural stability of the LNG storage tank.
